摘要

摘要:
排污许可证制度是目前普遍采用的水环境管理的重要制度之一，在水污染控制和水环境质量改善中发挥着重要作用。通过将基于水环境容量约束和基于流域排放标准的允许排放量进行对比，构建了控制单元排污许可总量限值管理模式和污染源排污许可总量限值优化方法。基于永定河流域典型控制单元的实证研究表明，在执行流域排放标准时，北京段典型控制单元可满足水环境质量改善需求，但张家口段典型控制单元仍需要削减COD_Cr 210.388 t/a。张家口段典型控制单元内2家污水处理厂上游间接排放固定源需分别削减COD_Cr 0.002和32.039 t/a。

Abstract:
Pollutant discharge permit system is widely used in water environment management, which has played an important role in water pollution control and water environment quality improvement. By comparing the allowable discharges based on the water environmental capacity constraints and the discharge standards for the watershed, the management mode of total discharge permit limit of control units and the optimization method of total discharge permit limit of polluting sources were constructed. The empirical study based on the typical control units of Yongding River watershed showed that the typical control unit of Beijing section could meet the needs of water environment quality improvement when implementing the watershed discharge standard, but the typical control unit of Zhangjiakou section still needed to reduce 210.388 t/a of COD_Cr. In the typical control unit of Zhangjiakou section, 0.002 and 32.039 t/a of COD_Cr should be reduced respectively in the two fixed sources whose wastewater was discharged into the sewage treatment plants.
